My interest is in Energy and Environment. Access to energy in many developing countries in Africa remains a major challenge. communities have no access to electricity and lack clean cooking fuels and technologies. There is need therefore to provide alternative energy from waste- biogas; geothermal; waves and improved cooking technologies. My carrier involves researching on sustainable alternative energy sources, train my students on how to innovate and manage the technologies. I have conducted two research in collaboration with two Profs. and one student in South Africa. One research was on waste to energy in Northern Province, this one is published, and the other one is on potential of biogas production from human waste, this has been submitted for publication.
